There can be no doubt that circular demand creates opportunities for circular supply. But how can closed loop criteria be integrated into public procurement, which represents nearly 14% of Europe's GDP? To figure it out, Renewable Matter interviewed Helena O'Rourke-Potocki and Simon Clement, respectively circular economy and procurement officer and senior coordinator on the circular economy at ICLEI – Local Governments for Sustainability.
ICLEI is a global network working with more than 2 500 local and regional governments committed to driving local action towards a social and ecological transition. In future, whether purchasing services or products such as buildings, furniture and food, local authorities will need to look for increasingly sustainable supplies.
The conference Towards a Circular Economy: Competences for Youth aimed to enable participants from different backgrounds to learn more about the outputs from the Circular Economy - Sustainable Competences for Youth (CESCY) project, to share their views and to hear from experts from different sectors.
The worsening climate crisis and the growing scarcity of natural resources have increasingly demonstrated the limits of our predominantly linear economy. There is no question that our business models and practices must become more sustainable and circular. It is therefore essential that young people be prepared to contribute and lead the way towards a more circular economy in Europe and beyond.
Bioforcetech aims to reduce energy and labour costs while reducing emissions and generating by-products (fertilisers) with added value. The company's vision is simple: instead of transporting "waste", machines are designed to transform organic streams into renewable energy and biochar right at the wastewater plant.
Food waste causes loss of materials and energy, environmental damage and negative effects on people's health and quality of life. In response to this, two Italian consumers' associations have decided to provide a series of nationwide services and activities, investing in innovative tools that promote the information needed to curb daily food waste.
NP-bioTech uses a biocatalyst, adsorbed onto an inert material (catalytic substrate). This enables the accelerated fermentation of critical biomass (such as citrus pulp or sewage sludge), transforming it into a biostabilised and pasteurised material with excellent agronomic properties.
The HOOP Network of Cities and Regions seeks to facilitate the exchange of knowledge and mutual learning among cities and regions willing to recover valuable resources from urban bio-waste and wastewater to make bio-based products.
By joining the network, cities and regions gain information about innovative urban bioeconomy solutions and engage in activities relevant to their context and specific interests. Participants have direct exchanges with the eight HOOP lighthouse cities and regions, sharing experiences and expertise.
The HOOP network is only open to organisations that plan, organise or operate municipal waste management or wastewater treatment activities, for instance local or regional authorities and waste management companies.
What are your plans for May? ACR+ will kick off an entire month dedicated to innovation and circular economy in waste management. Through several events, ACR+ will showcase some of its activities and projects fostering innovative approaches and practices to reach a circular economy.
Urban agriculture comes with its own share of environmental impacts. Circular strategies promise to reduce these impacts, but not all strategies are resource efficient and environmentally effective.
This paper finds that the most eco-friendly and circular strategies for urban agriculture, taking a Mediterranean tomato crop as a case study, include:
Struvite (phosphate mineral recovered from wastewater treatment) instead of non-renewable phosphate fertiliser to conserve freshwater
Recycled steel and materials for urban agricultural infrastructure to reduce carbon emissions, toxicity and freshwater pollution
Closed-loop irrigation to minimise ocean and freshwater pollution. However, if new infrastructure is required, it could lead to an increase in carbon emissions.
